Anyone has seen in work a fractional power of unit, different than square root?

Many nuclear reaction rates are modeled in series expansions based on the 1/3 power of the temperature. In general, fitting formulas to measured phenomena will happily use any power you can imagine, if it gets the behavior right.
so the need for rational powers remains? I remember that one of the reviewers complained that rational powers are "too" much: Noel Belcourt said: (by the date of Thu, 8 Jun 2006 00:54:51 -0600)
8) Is there an easy way to replace the rational dimensions with integers? A number of disciplines could probably make do with integers and paying for rational dimensions seems expensive and unnecessary, although it's certainly more general.
Assuming that we want both rational and integer powers - is thare any way to make it without making the library "too" complicated?
Difference between torque and energy happens only during serialization (print N*m, or print J ?), so maybe instead of complicated abstract_quantity_id, there should be just some extra argument/setting that will talk with serialization functions?
I think that this argument still stands? removing abstract_quantity_id would simplify the design... -- Janek Kozicki |
